To all whom it may concern.: a gate or opening G1 at the end of the same `Be it known thatv I, Louis V.

T e similar valved regulator ipes R3 R4l and R,i are provided connecting t e vapor spaces 'of the other compartments in series.

.'Figs.,2 andB "upon the brich work A which is The compartments may be heated to the desired extent in any way: As is seen in the chambers1 are mounted rovided by which they may be heated in the ordinary manner. It' is very desirable to employ a current producer of some description to main- Aso tain the roper circulation of fluid throu hout thee ongated conduit of this still an if' desired the chambers may be inclined to aid thi's'iiow. The current producer may he of the rotary form indicate in Figs. 1 and 3 in which two'shafts E VE2 are indicated passing longitudinally'through the chamber, preferably slightly above the upper edge of the partitions G. The shaft Fl1 1 s provided with paddles 'H1 which enter every alternate `cha'nnelof the conduit and are rotated inthe direction indicated by the arrow in Fig. 3. The other similarshaft E2 is also provided Withpaddles .H2 which enter the other channels of the conduit and by their rotation in the direction indicated Amaintain a circula tion of Huid throughout the whole staggered conduit. l A lrotary current producer of this description also very eil'cctivein preventing the -stratification of the f iuid in the conduit and produces a uniform flow of material lthrough the condult in conjunction with the submerged gates Grl inthe partitions. As is indicated in Fig. 1,. the partitions G in the several chambers are preferably spaced apart at different distances so as to allow for the evaporation of the material in these compartments as it passes through tlieni in series. The conduit may also,i desired, have a varying width or cross-section in a singleA cham er or compartment to allow for the diminution of the material flowing therethrough and t'liis may be accomplished, of course, by varying the spacing of the partitions in suoli chamber or compartment.

The current producer may be of the form indicated in Fig. 6 in which four sets of paddles KK K3 and K4 are indicated mounted upon appropriate shafts. Two of these sets of paddlesA K, and K3 rotatein the same direction 'and operate in the same alternate channels ci the conduit. The paddles K, and K, upon the other sha-its rotate in o posite directions und operate in the other c annels of the conduit to cause a' continuous flow of material through the staggeredelongated con d uit." lf desired, however, the cur-A rent producer may be formed in other ways, such, for instance, as is indicated in Figs. 2, 4 and in which a reciprocating current'producer is illustrated. A series rif-paddles Fz are illustrated in those figures, preferably ivotally mounted about' the pins F8 in the Ear F. This bar reciprocate-s across the tops of the partitions and is provided with suitable wheels or groovcd rollers F1, F4'Which engage the tops of `the artitions and are guided by the top guides r', G4, as illustrated in Fig. 5.' These paddles F2 swingoutward in every alternate channel of the conduit as the current producer'is reciprocated, the

paddlestaking the position in .4 when the current producer moves inthe The paddles in the direction of the arrow. l other channels fold together into the ino erative or feathcring position so that the uid icated in Fig.-v

is positively urged forwardin every alternate channel of the conduit at each niovemcnt'of thccurrent producer. As the current pro?" duc-er moves in the opposite direction, the iaddles swing outward and become eiective in the other channels to urge forward the 'material therein While the paddlewhich are shown in their extended position 1n Fig.,4

fold inward into their feathering positionffA This current roduccr may be reci rocated by any desire means. The oscillatingshaft l", may be' mounted in suitable hearings in the top of the. chamber, as imlicated-inFig. ".2, and may be provided with the arms. F s

secured thereto. The rods F9 tc'lesco e with the arms li", and these rods are pivote to the bar F so that as the shaft F, osciliates the ous manner.

ln the opi-ration oi this still the material, such, for. instance, as a heavy mineral oil, 1s

` supplied to the lirst compartment of the se- 110 current producer' is reciprocatcd in an obvi.

heavier .materials being removed from time to time, if desired, by the traps in the oil. pipes between the chambers. Thesetraps also allow for the disconnection of one of the .chambers in case oi' necessity, since, for inthe regulator valves may be opened and the vapor pressure'may thereby bekopt at the. proper amount in the several compartments and the `regular and proper flow of material from compartment. to compartment may thus `be insured. j

Itis, ofcourse, understood thatmany variations' may be made in this apparatus without de arting from the. spirit of thisinvention. Yariations may be made by `those skilled in theartin the proportion and size of the arts and in the number` of elements whic may .be employed. Furthermore, parts of this apparatus may be omitted and parts maybe used in connection with other devices Without sacrificing the advantages of this invention'. I' do not, therefore, desire to be limited to the disclosure which has been made in this case,but
